Runner's Knee
A new course record was set at the Chicago Marathon last year. With a
time of 2:04:38, Tsegaye Kebede became the first Ethiopian man to win on
Chicago’s flat course. Thousands of
first-timers and other runners followed the elite runners this morning. For these endurance athletes, training is
essential to reach the finish line, but overtraining or overpacing can easily
lead to injury. One common
running injury is known as runner’s knee (patellofemoral pain syndrome) which is
associated with pain behind the kneecap.
It is an overuse injury often seen in runners and cyclists, but it can
also be seen in sports which require repetitive jumping or cutting. While this pain can be cause by a direct
impact injury, it is typically caused by repetitive bending of the
knee.
The major symptom is pain
which usually begins as a dull ache or stiffness behind the kneecap
(patella). The patella is attached to
the thigh by the quadriceps muscle and tendon and to the leg by the patellar
tendon. Injuries or weakness of these
supporting structures can lead to improper alignment and tracking of the patella
as the knee bends and straightens. This results in irritation and
pain.
Conservative treatments for
patellofemoral pain syndrome begin with reduced training, ice, and
anti-inflammatory medication.
Incorporate stretching and strength training of the quadriceps and
hamstrings to improve stability around the knee. In addition to these therapies, custom arch
supports (orthotics) may be considered.
Recent studies have provided
evidence that orthotics reduce patellofemoral pain by improving the tracking of
the patella during the bending motion of the knee.
Although orthotics have been generally thought to benefit individuals
with excessive collapsing of the arch (over pronation), these studies have shown
that people of all foot types have reduction in knee pain with orthotics when
compared to flat inserts.
Patellofemoral pain syndrome
is a degenerative condition that can progressively get worse over time. Proper training and conditioning can help
prevent this and other lower extremity injuries. Following any injury, the goal of returning
to activity as quickly and safely as possible can be achieved with proper
evaluation and treatment. Custom
orthotics casted by a podiatrist can be an important addition to the
standard treatments for runner's knee.
